I can't believe that no part of the Paraguayan Chaco qualifies! I thought of it, but it's so dry that I thought there was no way it was worth putting in.
its because the technical definiton of a desert is not warm, it is based on wether a place gets less than a specific amount of rain. Canada, russia having such cold areas rain wouldn't be in the form of rain just snow and ice. Antartica is actually the worlds largest desert
Definitely there are no deserts in Brazil, therefore the country should be on the list.
The Brazilian northeast is semi-arid but not desert. Here is Wikipedia's definition of such climate: "A semi-arid climate or steppe climate is the climate of a region that receives precipitation below potential evapotranspiration, but not as low as a desert climate." (https://en.wikipedia.org/wiki/Semi-arid_climate)
I used this Wikipedia map as a source, and it shows small areas with a desert climate near the Sao Francisco river. I was surprised myself but, if you look at Google Maps, you can see it's really arid there indeed!
It's true that not all of the countries missing have areas with the typical appearance of, let's say, the Sahara desert (huge sand dunes, no vegetation at all etc.). However, according to the most widely used climate classification system, they do have areas with a desert climate, essentially proper deserts. Indeed, you can see that this place in Canada, for example, is pretty much a desert, in spite of the scanty shrubs!
The Wikipedia page listing all countries of the world by area gives a figure of 323,802 square km for Norway, but I just noticed they list Svalbard separately for some reason. This figure is used in other featured quizzes too though, so I'll leave it up to the Quizmaster.
@Gumbledalf It's there, in the Iran/Turkey border area, close to Armenia. Maybe it's not that easy to tell if it extends into Turkey but Wikipedia's Turkey-specific climate map confirms it.
Specify if you are including territories - the island of Nuku Hiva in French Polynesia is treelessly dry in the north and well below the level you qualify as desert, making it so that France does not count.
It seems that, according to Wikipedia, the "desert" part of Nuku-Hiva gets 510 mm of rain per year. I don't know how the rain is distributed throughout the year, but even in the most "desert-like" scenario the annual rainfall would have to be below 420 mm for it to classify by the criteria used here.
The extreme northern horn of Scandinavia, including part of Sweden and a tiny part of Finland, gets less than 400 mm of rainfall a year, so, I think this logic is then inconsistent to include Finland and Sweden but to omit other northern countries like Russia and Canada. No?
@bostjan: The Koppen classification for a desert climate that is used here depends on three variables: precipitation, its yearly distribution and average annual temperature. Low temperatures in polar regions counteract low rainfall, which is why the bitterly cold arctic Russian town of Verkhoyansk is surrounded by forest in spite of only 180 mm of annual precipitation. Russia and Canada are not excluded because of their polar regions, but because of dry areas near their southern borders.
Typical for my mind. I know almost all of the top half of the list (list of how often guessed), knew barely half of the 2nd part....but had Paraguay the first try. Sometimes i don't get my own logic. :P
The figure for France includes overseas departments, but dependencies are generally excluded. I think the only difference would be the inclusion of Denmark due to Greenland's size, as polar deserts are not taken into account.
There were some real surprises to me as far as larger countries that did NOT make this list.

Everything I saw was flat and grassy.
